New York (CNN) -- Former U.S. President Bill Clinton plans to visit Haiti on Wednesday to discuss the recent cholera outbreak and efforts to rebuild after a punishing earthquake, the Clinton Foundation said.

An outbreak of cholera has killed more than 2,000 people and sickened nearly 100,000 in Haiti, which still is reeling from an earthquake in January that killed about 220,000 people.

The country's Provisional Electoral Council said former first lady Mirlande Manigat finished first in the November 28 vote, followed by Jude Celestin, the candidate backed by outgoing president Rene Preval.

Since no candidate won a majority, the council said, a runoff election will be held on January 16.

The candidate that the council said finished third, musician Michel Martelly, alleged fraud and said that he won the election.

Martelly has proposed a fresh round of voting and said the troubled electoral council should be dumped. His supporters have protested the election results.
